load testing

Load Testing: A type of performance testing conducted to evaluate the behavior of a component or system with increasing load, e.g. numbers of parallel users and/or numbers of transactions, to determine what load can be handled by the component or system.

Load testing is a type of testing intended to determine the responsiveness, reliability, throughput, and scalability of an application. Apache JMeter is an open source application originally designed to test web applications but has evolved to work with many server and protocol types.
